         24 . The composition of  claim 23  wherein (a) and (b) are employed in a ratio by weight of from about 1:9 to 9:1.  
     
     
         25 . The composition of  claim 23  wherein (a) and (b) further comprise a substance selected from the group consisting of lecithins, phospholipids and mixtures thereof.  
     
     
         26 . Microcapsules containing the antioxidative composition of  claim 23 .  
     
     
         27 . The microcapsules of  claim 26  wherein the microcapsules have a mean diameter of from about 0.1 to 5 mm.  
     
     
         28 . The microcapsules of  claim 26  wherein the microcapsules comprise a membrane and a matrix containing the antioxidative composition.  
     
     
         29 . The microcapsules of  claim 26  wherein the microcapsules are produced by preparing a matrix, optionally dispersing the matrix in an oil phase, dispersing the matrix in a solution selected from the group consisting of an aqueous anionic polymer solution and an aqueous chitosan solution and optionally removing the oil phase.  
     
     
         30 . The microcapsules of  claim 29  wherein the matrix contains: 
 (i) gel formers;    (ii) an ingredient selected from the group consisting of anionic polymers, chitosans and mixtures thereof; and    (iii) (a)+(b).    
     
     
         31 . A process for treating human skin comprising orally ingesting or topically administering onto the skin an antioxidative composition containing: 
 (a) an active component selected from the group consisting of (i) at least two extracts selected from the group consisting of  Vaccinium myrtillus, Trifolium pratense, Vitis vinifera  and  Thea vinensis;  (ii) at least two active components selected from the group consisting of anthocyanosides, isoflavone glucosides and polyphenols; and (iii) mixtures thereof; and    (b) a co-active component selected from the group consisting tocopherol, ascorbic acid and mixtures thereof.    
     
     
         32 . The process of  claim 31  wherein (a) and (b) are employed in a ratio by weight of from about 1:9 to 9:1.  
     
     
         33 . The process of  claim 31  wherein (a) and (b) further comprise a substance selected from the group consisting of lecithins, phospholipids and mixtures thereof.  
     
     
         34 . The process of  claim 31  wherein the antioxidative composition is administered in the form of microcapsules.  
     
     
         35 . The process of  claim 34  wherein the microcapsules have a mean diameter of from about 0.1 to 5 mm.  
     
     
         36 . The process of  claim 34  wherein the microcapsules comprise a membrane and a matrix containing the antioxidative composition.  
     
     
         37 . The process of  claim 34  wherein the microcapsules are produced by preparing a matrix, optionally dispersing the matrix in an oil phase, dispersing the matrix in a solution selected from the group consisting of an aqueous anionic polymer solution and an aqueous chitosan solution and optionally removing the oil phase.  
     
     
         38 . The process of  claim 37  wherein the matrix contains: 
 (i) gel formers;    (ii) an ingredient selected from the group consisting of anionic polymers, chitosans and mixtures thereof; and    (iii) (a)+(b).
